vSphere host update utility proxy configuration

Quite a few folks are running Vmware Vsphere behind the corporate firewalls. We do the same and experienced some problems with Host update utility.

It was quite hard to figure out how to specify the proxy settings so that our Host Update utility can easily check Vmware update servers (for folks who want to open direct access the update server name is hostupdate.vmware.com ) for latest patches.  So we finally figured it out and here are the necessary steps:

Open the VIUpdate folder (in our case: C:Program FilesVMwareInfrastructureVIUpdate 4.0 ) and find file named settings.conf

Open it in text editor and do the following config:

<?xml version=”1.0″ encoding=”utf-8″?>
<add key=”RemoteDepot” value=”https://hostupdate.vmware.com/software/VUM/PRODUCTION/index.xml” />
<add key=”AskBeforeDownload” value=”True” />
<add key=”ProxyServer” value=”“/>
<add key=”LocalDepot” value=”C:Documents and SettingsAll UsersApplication DataVMwareVMware VI Update” />
<add key=”UserSettingsDirectory” value=”C:Documents and SettingsAdminApplication DataVMwareVMware VI Update” />

By default ProxyServer key will be left blank. In my case I set-up a proxy host with port 8080.

    What is the syntax to enter my proxy user ID and password?

    Unfortunately, I didn’t find the way to enter username/password. Is it possible that you set-up your proxy not to require username/password ?

    I used NTLMaps (http://ntlmaps.sourceforge.net/) to bypass ISA authentication and specified as a proxy in settings.conf. Works like a charm!
